WhatsApp Messenger, or simply WhatsApp, is a freeware, cross-platform messaging and Voice over IP service. It is presently owned by Facebook, Inc.
It allows users to send text messages and voice messages, make voice and video calls, and share images, documents, user locations, and other media.
From time to time on my website, I like to look at tools that would help you make more sells and get more traffic to your website. And, WhatsApp is a tool we should not ignore.
